The ICON Dodge Ram 1500 rear coil springs provide 1.5″ of lift height and feature a dual rate design with ICON-engineered ride and overload rates. This dual rate design allows for a soft rate at ride height for superb on-road comfort and a firmer secondary rate that increases during compression for excellent payload support, bottoming resistance, and off-road performance. Like all ICON coil springs they feature a lifetime guarantee against sagging/breakage to produce confidence in knowing that you have the best suspension products available for the 09-UP Dodge Ram 1500.Additional Attributes:GTIN:00840103400549Color:BlackFinish:PowdercoatedSpring Material:SteelMaximum Lift Height:1.5Spring Color:BlackGrade Type:PerformanceRear Spring Seat Included:NoRear Spring Rate Type:VariableAAP_UDA_12:EAAAP_UDA_22:1AAP_UDA_4:55California Proposition 65:WARNING: This product contains chemicals known to the State of California to cause cancer, and birth defects or other reproductive harm.Extended Information:Emissions :Emissions Compliance ExemptLife Cycle Status:Available To OrderPackaging:Quantity of Each:1.0Package UOM:EADimension:21.0000 x 13.0000 x 7.0000 inchesWeight:40.0000 PGPDF:I212150_REVA
